Geokit
Geokit is a command-line interface (CLI) tool written in javascript, that contains all the basic functionalities for measurements, conversions and operations of geojson files.
Install Geokit CLI
Geokit is installed with docker, due several functionalities from other repositories like awesome-geojson were incorporated to Geokit functionalities.
- Building from repo
git clone [email protected]:developmentseed/geokit.git
cd geokit/
docker-compose build
alias geokit='docker run --rm -v ${PWD}:/mnt/data developmentseed/geokit:latest geokit'
- Building from docker-hub
alias geokit='docker run --rm -v ${PWD}:/mnt/data developmentseed/geokit:latest geokit'
Install for development mode
docker-compose run geokit
or
cd geokit/
docker run --rm -v ${PWD}:/mnt/data developmentseed/geokit:latest bash
Usage
Area
- Gets the total area in km² of polygon features that there are in a geojson file.
geokit area input.geojson
Bbox of FeatureCollection
- Gets the bbox of a FeatureCollection.
geokit bbox input.geojson
Bbox to FeatureCollection
- Converts a bbox to FeatureCollection.
geokit bbox2fc --bbox="0, 0, 10, 10" > output.geojson
Buffer
- Creates features' buffer for a given radius.
geokit buffer input.geojson --unit=meters --radius=10000 > output.geojson
Feature to square
- Creates features' square for a given radius in meters, in case of Polygon and LineString the script takes the centroid to generate the square
geokit fc2square input.geojson --radius=40 > output.geojson
Clip
- Gets only the features that are inside the given boundary and it deletes all features outside the boundary.
geokit clip input.geojson boundary.geojson > output.geojson
Distance
- Gets the total distance in km of LineString and MultiLineString features that there are in a geojson file.
geokit distance input.geojson
Line to polygon
- Changes the type of geometry from LineString to Polygon.
geokit line2polygon input.geojson > output.geojson
Set each feature into a row
- Sets each feature into a row from FeatureCollection.
geokit fc2frows input.geojson > output.json
FeatureCollection to CSV
- Adds an osm_download_link column per each feature and each link downloads the feature in JOSM.
geokit fc2csv input.geojson > output.csv
Add on each Feature
geokit addattributefc input.geojson --prop "type=hospital" > output.geojson
Filter features by property
- Filters features by given property and it will generate a new geojson file with the filtered features.
geokit filterbyprop input.geojson --prop building=* > output.geojson
Filter features by geometry
- Filters features by given one or many geometry types and it will generate a new geojson file with the filtered features.
<geometry_types>: Could be Polygon, LineString, etc.
geokit filterbygeometry input.geojson --geos <geometry_types> > ouput.geojson
Count features by property
- Gets the total number of features that exist inside the a geojson file (according to a chosen property).
geokit countfeature input.geojson --prop building=*
Set area on each feature in a geojson file
- Gets the area in m² of each feature (polygon) into a geojson file and it will generate a new geojson file with all features plus an area property.
geokit featurearea input.geojson > output.geojson
Set bbox on each feature in a geojson file
geokit featurebbox input.geojson > output.geojson
Set distance in kilometers on each feature in a geojson file
geokit featuredistance input.geojson > output.geojson
Count features by area size
- Counts features larger than the given area size in km². Applicable for polygons.
geokit countbysize input.geojson --psize=1000
Difference between two geojson files according to an attribute
- Gets the difference of the objects between two geojson files according to a common attribute.
--key: Could be any of attribute, which is in both files.
geokit difference <file1.geojson> <file2.geojson> --key=school_code
Keep attributes in feature
geokit keepattributes <file1.geojson> --keys="id,power,timestamp" > output.geojson
Rename key in properties
geokit renamekey <file1.geojson> --key="idBuilding>id" > output.geojson
Duplicate objects by an attribute
- Gets the duplicate objects, identified by a unique attribute or primary key.
geokit duplicatefeatures <file1.geojson> --key=id
Features to tiles
- Pass a geojson with points and get the nearest tiles to this point in a geojson file.
geokit point2tile <file.geojson> --zoom=17 --buffer=0.2 --copyattrs=true > tiles.geojson
Tile Cover
- Pass a polygon and get the tiles which cover all the polygon at a certain zoom. From: https://github.com/mapbox/tile-cover
geokit tilecover polygon.geojson --zoom=15 > tiles.geojson
Delete nulls
- Deletes the attributes that have a null value.
geokit deletenulls input.geojson > output.geojson
JSON to GeoJSON
- Gets a geojson file from json file.
geokit jsonlines2geojson input.json > output.geojson
Feature to point
- Gets the centroid for each features.
geokit centroid input.geojson > output.geojson
Remove objects with action=delete
- Removes the objects with action=delete in a osm file.
geokit removeactionosm input.osm output.osm
OSM file to new OSM file
- Removes some attributes of each feature such as:
user,version,timestamp,changesetanduid. So it returns a new OSM file without these attributes.
geokit osm2new input.osm output.osm
Split a file according to zoom level
- Divides the features into a geojson file according to a given zoom level (works for zoom <= 15), and it will generate geojson files into a folder.
geokit splitbyzoom input.geojson --folder=foldername --zoom=10
Other functionalities into a Docker image:
Functionalities outside Geokit into a Docker image.
geojson-merge
- Merges multiple geojson files into one FeatureCollection.
geojson-merge input1.geojson input2.geojson > output.geojson
XMl to CSV (CVAT's xml dump file)
- XML to CSV only for CVAT dump files
docker run --rm -v ${PWD}:/mnt/data developmentseed/geokit:latest geokit cvat-xml2csv --full=ok imput.xml
The comand line will filter all the boxes on each row in each image.
Note
Remove --full=ok from the comand line to filter only the images.
Downsized images
Add all the images that you want to downsize in a folder, supports jpg files and the files will be resized to 512X512.
docker run --rm -v ${PWD}:/mnt/data developmentseed/geokit:latest geokit downsized-imgs <FOLDER>
The output directory: <FOLDER>-downsized.
NPZ file to XML cvat imput format
docker run --rm -v ${PWD}:/mnt/data developmentseed/geokit:latest geokit cvat-npz2xml <labelMaker npz file>.npz --imgPath=<path of the images in CVAT> --imgLabel=tower
XML(CVAT format) to NPZ
docker run --rm -v ${PWD}:/mnt/data developmentseed/geokit:latest geokit cvat-xml2npz <cvat xml dump file>.xml
It will return a file with the same xml file name with npz extension.
Count number of tags in XML for CVAT dump files
docker run --rm -v ${PWD}:/mnt/data developmentseed/geokit:latest geokit cvat-count-tags imput.xml
osmtogeojson
- Converts osm file to geojson format.
osmtogeojson input.osm > output.geojson
geojsontoosm
- Converts geojson file to osm format.
geojsontoosm input.geojson > output.osm
geojson2poly
- Converts geojson polygons to OpenStreetMap (OSM) poly format file.
geojson2poly input.geojson output.poly
geojson-pick
- Removes all but specified properties from features in a geojson FeatureCollection.
geojson-pick PROPERTYNAME1 < input.geojson > output.geojson
dosm
- Download OpenStreetMap data for a polygon
